The forums usually turn into a war zone of players against Nexon whenever a bad memo or patch drops.
On the other hand, people who are happy rarely voice that opinion.
I suggest that Nexon expands upon the "post-game survey" that pops up sometimes when you exit maple.
Instead it would be a survey of questions that are important to Nexon, with a short comment available after questions.
This would allow Nexon to compile data that would be useful to itself without having to slog through hundreds of forum posts, reddit threads, discord servers, etc.
Of course there will be opinions expressed in these locations that the survey will not catch, but most dedicated players will answer a short survey if you place incentive behind it.
Offer players a small reward such as a few EXP coupons or Nodestones/Symbols for completion of the survey.
Use this data to give players more direct ways of giving their opinion on targeted areas that you're already looking to improve.
Of course the six month delay on patches does need to be accounted for, so it really is best if Nexon themselves hold this survey because only they know what they're about to look at in KMS or GMS.
This survey would best be given on the website as an opt-in rather than after closing the game.
Include this survey at the bottom of memos and a month or two after a major patch drops, to give players time to adapt.
Some Sample Questions:
With the latest Memo, we mentioned that we were going to adjust Kanna at some point in the future. Do you think Kanna is under powered, over powered or balanced?
In the latest patch, we revealed more of the Grandis storyline, did you think the story was well writen or too long winded?
We recently announced that we were going to revamp [GMS Specific Thing], what are your biggest concerns on this?

Even if we do not see the results of the survey data, this is still a more direct way of allowing players to voice their opinions and gives you the chance to actually be transparent with us.
Please Nexon, the community is willing to work with you if you just stop belittling us.
